Impact of a person-centred group intervention on life satisfaction and engagement in activities among persons aging in the context of migration‡

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Reducing loneliness among migrant and ethnic minority people: a participatory evidence synthesis

Background

To date, there has been little research into the causes of, and solutions to, loneliness among migrant and ethnic minority people.

Objectives

The objectives were to synthesise available evidence and produce new insights relating to initiatives that aim to address loneliness among these populations, plus the logic, functioning and effects of such initiatives.

Data sources

Electronic database searches (MEDLINE, Applied Social Sciences Index and Abstracts and Social Science Citation Index via Web of Science – no date restrictions were applied), grey literature searches, and citation and reference searching were conducted. Data were generated via nine workshops with three consultation panels involving 34 public contributors, and one practitioner workshop involving 50 participants.

Review methods

Guided by ‘systems thinking’, a theory-driven synthesis was combined with an effectiveness review to integrate evidence on the nature and causes of loneliness, interventional types and programme theory, and intervention implementation and effectiveness.

Results

The theory review indicated that common conceptualisations of ‘loneliness’ can be usefully extended to recognise four proximate determinants when focusing on migrant and ethnic minority populations: positive social ties and interactions, negative social ties and interactions, self-worth, and appraisal of existing ties. A total of 170 interventions were included. A typology of eight interventions was developed. Detailed logic models were developed for three common types of intervention: befriending, shared-identity social support groups and intercultural encounters. The models for the first two types were generally well supported by empirical data; the third was more tentative. Evaluation of intervention processes and outcomes was limited by study content and quality. Evidence from 19 qualitative and six quantitative studies suggested that social support groups have a positive impact on dimensions of loneliness for participants. Evidence from nine qualitative and three quantitative studies suggested that befriending can have positive impacts on loneliness. However, inconsistent achievements of the befriending model meant that some initiatives were ineffective. Few studies on intercultural encounters reported relevant outcomes, although four provided some qualitative evidence and three provided quantitative evidence of improvement. Looking across intervention types, evidence suggests that initiatives targeting the proximate determinants – particularly boosting self-worth – are more effective than those that do not. No evidence was available on the long-term effects of any initiatives. UK intervention (n = 41) and non-intervention (n = 65) studies, together with consultation panel workshop data, contributed to a narrative synthesis of system processes. Interlocking factors operating at individual, family, community, organisational and wider societal levels increase risk of loneliness, and undermine access to, and the impact of, interventions. Racism operates in various ways throughout the system to increase risk of loneliness.

Limitations

There was a lack of high-quality quantitative studies, and there were no studies with longer-term follow-up. UK evidence was very limited. Studies addressing upstream determinants operating at the community and societal levels did not link through to individual outcome measures. Some elements of the search approach may mean that relevant literature was overlooked.

Conclusions

Theory regarding the causes of loneliness, and functioning of interventions, among migrant and ethnic minority populations was usefully developed. Evidence of positive impact on loneliness was strongest for shared-identity social support groups. Quantitative evidence was inadequate. The UK evidence base was extremely limited.

Future work

UK research in this area is desperately needed. Co-production of interventional approaches with migrant and ethnic minority people and evaluation of existing community-based initiatives are priorities.

Associations Between Acculturation, Depressive Symptoms, and Life Satisfaction Among Migrants of Turkish Origin in Germany: Gender- and Generation-Related Aspects

OBJECTIVE

The aim of the present study was to investigate the degree of depressive symptoms and life satisfaction (LS) as well as the association between acculturation and depressive symptoms among a large sample of persons with Turkish migration background in Germany, taking into account gender- and migration-related differences.

METHODS

This study was part of a pretest for a large national epidemiological cohort study in Germany. Acculturation was measured using the Frankfurt Acculturation Scale (FRACC). Based on the median split of the two subscales, four acculturative styles according to Berry (integration, assimilation, separation and marginalization) were determined. Depressive symptoms were assessed with the depression module (PHQ-9) from the Patient Health Questionnaire. LS was assessed with a single item on a scale from 1 = bad to 5 = excellent. Differences in levels of depressive symptoms and LS in relation to gender and generation of migration were tested with analysis of covariance, controlling for age. Gender-stratified multiple linear regression analyses were also conducted for depressive symptoms as criterion variable.

RESULTS

328 Turkish migrants participated (61.3% women). The cut-off-value of ≥10 for the PHQ-9 was achieved by 33.2% of the women and 26.4% of the men (p=0.209, φ=0.071). In female migrants, the age-adjusted mean score for depressive symptoms was 7.81 (SD=6.42), in males 6.70 (SD=6.41) (p=0.137, η²=0.007). After controlling for unemployment status, women showed a trend for being more frequently depressed than men (p=0.055, φ=0.117) and also demonstrated a trend for higher levels of depressive symptoms (p=0.072, η²=0.012). No significant gender-specific difference was found concerning age-adjusted mean score for LS (p=0.547, η²=0.001), also when controlled for unemployment status (p=0.322, η²=0.004). In both sexes, the second generation demonstrated a significantly higher age-adjusted mean score for LS of small/medium effect size than the first generation. In women, separation as acculturation style (linear regression coefficient (B=4.42, 95% CI=1.68, 7.17, p=0.002; reference: integration), having no partnership (B=2.56, 95% CI=0.26, 4.86, p=0.03) and lower education (B=-2.28, 95% CI=-4.54, -0.02, p=0.048) were associated with higher severity of depressive symptoms; in men, separation as acculturation style (B=4.01, 95% CI=0.70, 7.31, p=0.018; reference: integration) and employment status (B=-3.32, 95% CI=-5.71, -0.92, p=0.007) were related to depression levels.

CONCLUSIONS

Separation as acculturation style is associated with higher levels of depressive symptoms (for both genders). Gender-sensitive health promotion programs should target separated migrants to improve their integration into the German society.
